After I had my time-out with the blanket I decided the best way to join the squares was to keep with the white and whip-stitch them together. It went pretty quickly and I was happy to get it done, Once I attached all of them I did a simple border of just single crochet around in white yellow and black. It's not a very large blanket but I really did enjoy making the different squares and watching it come together. Now that I've finished the blanket I'm happy to say I will definitely be attempting more c2c graphgans in the future!
If you are looking for the graphs you can find them here.
Stay tuned, there will be a GIVEAWAY on the blog very soon for my 100th post!
